scope:

This standard describes the requirements and inspection methods for measuring the effective case depth of ferrous powder metallurgy products.

In order to determine effective case depth the procedures for determining the microindentation hardness of powder metallurgy materials, as described in MPIF Standard 51 shall be followed.

The values stated in inch-pound units are to be regarded as the standard. Values in SI units are shown in parentheses and result from conversion in accordance with IEEE/ASTM Standard SI 10. They may be approximate and are only for information.

This standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the potential safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
